More About This Product

DG05Trimix/CCRDG05 is a technical dive computer for the growing technical diver. Whether you are advanced nitrox looking towards Trimix or an avid CCR diver, the DG05 will provide you the platform to modify based on your diving needs. Benefit from the only Trimix dive computer capable of monitoring up to 4 independent transmitters. Includes a vibrant OLED display and the freedom of a variable decompression model VGM all encased in a rugged mil-spec aluminum case. Accepted by NOAA for use by NOAA Divers.

Ready for anything, from air to trimix, OC,SCR and CCR capableSimple to use menu system with easy to read Icons and auto detect functionsOptocon (IR transmission of PO2/PC link) No more wet connectorsVGM algorithm allows you to customize your parameters or mimic other commercial algorithms on your ownAutomatically switch to large graphics mode - menu bar disappears after a few seconds and the primary dive information fills the screenRechargeable lithium-ion battery

The VGM algorithm is built on recent practical dive planning and diving techniques as well as the scientific and theoretical understanding. It combines theoretical knowledge of bubble physics together with known diving practices. VGM also gives the user the ability to change the conservatism to increase or decrease decompression times. VGM incorporates 5 main features:Buhlmann decompression modelModification of tissue over pressure tolerances or M values for the faster tissues to create a decompression profile similar to a bubble model like VPMFurther modification of over pressure tolerances for deep or long exposure dives, especially in the fast and middle order tissuesAutomatic adjustment of the above parameters to allow the default settings to give common decompression and No Stop times across the range of diving from 10m to 120mUser adjustable parameters - the diver can use his/her experience to further modify the decompression to that which suits him/her. The Equivalent Gradient Factors are displayed for a particular dive for ease of comparison with other dive computers and dive tables. However, because this system goes beyond Gradient Factors certain adjustments may only give an estimate of the GF equivalent.
